[How To]: extend time for deleting temporary files in tmp directory on Ubuntu 10.04 LTS

Posted on by
Reply

Temporary files located on /tmp directory will be deleted by default with every time you restart or shutdown from ubuntu 10.04 LTS. It becomes handy some times if you want to keep your tmp files for some applications already installed in your machine in case you want to use it later.

Open this your filesystem directory /etc/default/rcS Open this file

In line 10 you will find ” TMPTIME=0 ” by default the value is zero that value delete temporary files with every time you restart the machine.

If you want to keep your files for ever make the value ” TMPTIME=0 ” with negative number. ” not recommended it will  ”

If you want to keep temporary file for two days, change the value to be ” TMPTIME=2 ”

so that’s for now :)

[How To]: Get the best performance with SUN VirtualBox

Sun virtualBox one of the best virtualization applications you can use to run multiple operating system in the same time, but it need some dependencies to get better performance in your operating system whatever the operating system is Ubuntu, Mandriva, Fedora, Centos, …… I am using it now on Ubuntu.

Ubuntu Swap, ” check your operating system Swap ”

really important because it used as same as your installed memory RAM, check this post for ubuntu Swap improvement, just make sure your swap size at least as same as your installed memory RAM.

for system setting you raise to the half memory you already have, for that if raised more than you have the Swap will help to keep you system stable.

also you can use multiple cores if you have multiple core processor. If you have a decent machine you can active full acceleration.

set the display memory depending in you graphics card performance, if you want to get 3d, 2d visualizations it might slow down the virtual machine.

that’s it for now.

simply you can install it by terminal

sudo apt-get install cameramonitor

More information and download options for other distributions

3. Camorama

camorama is a program i wrote to learn gtk and v4l. as you can see, i am still learning ;) . it is pretty simple at the moment, and i hope to make it much more complete. i also plan to make it more generic, as i initially wrote it with only my own creative webcam 3 in mind. hopefully it will work with other cameras. i will test on anything i can get my hands on, but that might take a while.
right now you can change the video settings using the gui and apply some crappy filters i wrote to mess around with. it runs at a reasonable speed, but i would like to get the fps up as high as possible. still figuring that out.
as for requirements, you will need at least gnome 2 and v4l. i haven’t used anything else crazy, and that should do it.

More informations and Download Options

4. Gnome Security Camera “Gspy”

Gspy retrieves images from a video4linux device and processes these into a daily mpeg movie on the disk drive. Each image is recorded with a time stamp to insure accurate real world correlation. Special motion detection algorithms are used to reduce the size of the daily movies by eliminating pictures with similar content as well as the normal compression obtained via the mpeg process. The result is a time lapse video per day with nonlinear time compression using only the images of interest. This program will only run on Linux machines which support a video4linux-device in 640×480 capture size. This software has been tested with the 2.4.0-test1 kernel, 2.4.0-test4 and the 2.2.16 kernel with the usb backport patch. You should have the Berkeley MPEG Tools installed if you wish to generate the MPEG files. Gspy can be used without the MPEG tools, as it will fill a directory with jpg images that can be processed or viewed at a later time. Versions from 0.1.6 include a user defined command that is executed on each alarm. This command string can include a token(s) “%f%” that will get replaced with the alarm picture filename. Typical uses would be to copy the alarm picture to a remote site using ftp or scp, email the picture to someone, play a sound annoucement… “Step away from the keyboard!”, turn on lights using a parallel port or X10 interface, or ???. Have FUN

How to add repositories on Ubuntu 9.10

Posted on by

Common applications installed using synaptic package manager already installed by referring from default repositories added on ubuntu 9.10 or any other version it’s the same way to add extra repositories for other distributions such as ubuntu 10.04 LTS beta 1

Default repositories on ubuntu monitored by ubuntu community, so in this post i will show you how to add extra repositories for ubuntu 9.10 and 10.04 LTS beta 1 as well.

1. Adding repositories

you can get access to it using:

a.  synaptic package manger

System menu  —> Administration —> Synaptic —> Settings —> Repositories

b.  System menu —> Administration —> Software Sources

Common repositories already added on software sources by ubuntu and kubuntu. some application need to add extra repositories to be able to install it in your machine, will use this as example

deb http://ppa.launchpad.net/moovida-packagers/ppa/ubuntu karmic main

access the software sources, will ask you for root password then go to other software and press add button and paste the apt line like this one up there

If you want to backup all repositories you already have type this command on terminal

sudo cp -i /etc/apt/sources.list /etc/apt/sources.list_backup

This will copy you repositories list to this folder “./etc/apt/ ” with name called sources.list_backup

2. adding repositories key

some application need repositories key to get rid of so warning massages during the installations

so you will find more instructions on the website for installing this package and it will mention repositories key you can add it directly from the terminal.

That’s it for now. :)

Hello guys,







I think when ubuntu 9.10 released system menu icons was hidden with default release, as same as with ubuntu 10.04 beta 1


it’s old trick for who don’t know it so there are two ways to get these icons back.







1st


open terminal and type




gconftool-2 --type Boolean --set /desktop/gnome/interface/menus_have_icons True




2nd







open configuration editor from system tools


if you can’t find it open terminal and type




 gconf-editor









then go to Desktop –> Gnome –> Interface











you will find “menus have icons” make this value true


that’s it


 :)
